Oh dear. This is a loss. Rest in peace.
If you're not familiar with Bill Rieflin's work, the fan comment at this link gives you an idea of just how good a drummer he was.
The obituary doesn't mention his work with Robyn Hitchcock and the Venus 3.
Fanboy thing: Rieflin notoriously was reluctant to give autographs, but I did manage it on Ole Tarantula, Peter Buck was most surprised when he saw it when signing below it!
